Ludwig von Bertalanffy

Karl Ludwig von Bertalanffy (19 September 1901 – 12 June 1972) was an Austrian biologist known as one of the founders of general systems theory (GST), the "conceptual part" of which was first introduced by Alexander Bogdanov.[citation needed] This is an interdisciplinary practice that describes systems with interacting components, applicable to biology, cybernetics and other fields. Bertalanffy proposed that the classical laws of thermodynamics might be applied to closed systems, but not necessarily to "open systems" such as living things. His mathematical model of an organism's growth over time, published in 1934, is still in use today.[1] Bertalanffy grew up in Austria and subsequently worked in Vienna, London, Canada, and the United States.
